I have Ford Ranger 2004 Model my battery was flat now my radio cant play it says it needs a code.
Unhook the battery.
Unhook the car battery.
Yes, most definitely.
Just hook up the charger to the battery while it is still in the car and do not unhook it.
You could accidentally short out the power wire to the radio and blow a fuse. But you really do not have to disconnect the battery terminal. Just remove the fuse for the radio circuit and you will be fine.
Unhook battery cables to reset and then when you turn radio on again just type the code using the numbers 1-6
call your orig dealer and ask for the radio code if you dont have it i think the radio gives you 2 or 3 attemtps to input the radio code, if you dont get it right it will lock you out....if that happens, unhook car's battery and reconnect ...when you turn on the radio, you will then be prompted to enter the radio code. hope this helps
If you are referring to the ecu then if you have an unlock code for the radio you can unhook the battery for a while. If not go by your local autozone and they can clear any codes
there is no reset button....u can unhook the battery or the fuse located in the fuse box under your left knee when sitting in the driver sit
I worked on an 89 and what I did was unhook the negative connection to the battery and leave it off for 15 minutes. The reconnect it. You will need to fix the time and radio channels but normally the computer is reset
